The Sorbian alphabet is based on the ISO basic Latin alphabet but uses diacritics such as the acute accent and the caron, making it similar to the Czech and Polish alphabets. The standard character encoding for the Sorbian alphabet is ISO 8859-2 (Latin-2).
The alphabet is used for the Sorbian languages, although some letters are used in only one of the two languages (Upper Sorbian and Lower Sorbian).
An earlier version of the Lower Sorbian alphabet included the use of the letters b́, ṕ, ḿ, and ẃ to indicate palatalized labials. These have been replaced by bj, mj, pj and wj.
Sorbian orthography also includes two digraphs:
The digraph ch follows h in alphabetical order.
